This volume includes highlights of the design of the Mark IIA uniprocessor (SMI-2), and the SCALD II user's manual. SCALD (structured computer-aided logic design system) cuts the cost and time required to design logic by letting the logic designer express ideas as naturally as possible, and by eliminating as many errors as possible - through consistency checking, simulation, and timing verification - before the hardware is built.

The Biocide By-Products in Aquatic Environments Program is composed of analytical chemistry and biological phases with freshwater and marine biological subdivisions. The objectives of the analytical studies are: to identify those chloroorganic chemical compounds that result from the addition of chlorine to fresh or saltwater; to develop methods for detecting chlorinated organics in the effluents discharged to receiving water bodies from nuclear stations; and to verify laboratory findings through analysis for chlorination by-products in water and biota samples from cooling water bodies of nuclear power stations. The objectives of the biological studies are: to investigate the immediate toxicity of specific chlorination by-products (chloroform in freshwater and bromoform in marine waters); to evaluate the chronic toxicity of chlorination by-products; to follow their pathways of action; and to analyze for bioaccumulation or biomagnification of halogenated hydrocarbons on selected aquatic or marine biota.

The status of the programs and projects of the Electronics Division for the period July through December 1978 is reported. The presentation is divided into three sections: Research, Engineering Support, and Technical Services. Each of these sections presents the activities and accomplishments of the corresponding branch within the Division. The primary goal of the Research and Development branch is to advance technology for future applications. The primary goal of the Engineering Support Branch is to apply advanced technology to Laboratory and material problems. The primary goal of the Technical Services Branch is to provide a technical base and support for Laboratory programs. Most of the individual reports are quite short.

This paper describes apparatus that will be used to provide 200 kW of microwave heating at 28 GHz to the ISX-B tokamak.

This experimental stress analysis evaluates polystyrene bead foam (PSBF) as an encapsulant. Direct comparison data are included for polyurethane foam encapsulation. Thermal stresses on solder joints using a thumb tack test are compared for these foam encapsulants and GMB/epoxy. Special transducer designs are used to measure thermomechanical stresses and deflections. Failure criteria for some of the electronic components involved are delineated. The mechanical properties of potting polystyrene bead foam is presented and compared with the properties of structural polystyrene bead foam. The thermomechanical load and deflection data and the transducers developed are aids for making stress analysis in other foam encapsulated units. Polystyrene bead foam is concluded to be a safe encapsulant for certain electronic packages, but polyurethane foam is not.

This report contains the feasibility study, economic analysis, and information relevant to reactivation of the dam in Bethelehem, NH. It outlines a plan of development which calls for sale of the power to a local utility for the first few years of the project and then predominately on-site use of the power in an innovative plan for controlled-environment agriculture. The economic analyses indicate that reactivation of the dam would be a successful venture based on the present market value of 4.5 cents/kWh. The success of the second phase in the dam's use rests on the increasing financial attractiveness of locally grown produce in a state that currently imports over 90% of its food and is experiencing the spiraling costs of food, energy, and inflation. The best-suited turbine package for the site is an Ossberger 750-kW unit which would provide 4,014,000 kWh per year with a plant factor of 61%. The total capital costs of the project are $827,935.

Abstract: A Final Environmental Statement for the Power Authority of the State of New York for the construction of the Greene County Nuclear Power Plant (Docket No. 50-549) located in Greene County, New York, has been prepared by the Office of Nuclear Reactor Regulation of the Nuclear Regulatory Commission (NRC). This statement provides (1) a summary of environmental impact and adverse effects of the proposed facility, and (2) a consideration of principal alternatives. Also included are comments of governmental agencies and other organizations on the Draft Environmental Statement for the project and staff responses to these comments. The NRC staff has concluded, based on a weighing of environmental, economic, technical, and other benefit against environmental costs and available alternatives, that a construction permit should be denied because the alternative sites available to the applicant are environmentally preferable. If the permit is granted, the applicant will be required to take the necessary mitigating actions to decrease the aesthetic impact by using alternative closed cycle cooling systems and to undertake monitoring programs to identify, evaluate and mitigate construction related community and public services impacts in the immediate three-county impact area.

The overall objective of the LSA Silicon Material Task is to establish a chemical process for producing silicon at a rate and price commensurate with the production goals of the LSA project for solar-cell modules. This material must be suitable for utilization in the large-area sheet process and in the automated process for the fabrication of solar cells. As part of the overall Silicon Material Task, Union Carbide developed the silane-silicon process and advanced the technology to the point that it has a definite potential for providing high-purity polysilicon on a commercial scale at a cost of $14/kg by 1986 (1980 dollars). The Phase III program (initiated in April 1979) is aimed at establishing the practicality of the process by pursuing the followng specific objectives: (1) design, fabricate, install, and operate an Experimental Process System Development Unit (EPSDU) sized for 100 MT/Yr to obtain extensive performance data to establish the data base for the design of commercial facilities; (2) perform supporting research and development to provide an information base usable for the EPSDU and for technological design and economic analysis for potential scale-up of the process; and (3) perform iterative economic analyses of the estimated product cost for the production …

The design, fabrication, and testing of two sizes of power crowbar transformers for the ZT-40 Toroidal Z-Pinch experiment at the Los Alamos Scientific Laboratory are described. Low-leakage transformers in series with the poloidal and the toroidal field coils are used to sustain magnetic field currents initially produced by 50-kV capacitor banks. The transformer primaries are driven by cost-effective, ignitron-switched, 10-kV high-density capacitor banks. The transformer secondaries, in series with the field coils, provide from 1,000 to 1,500 V to cancel the resistive voltage drop in the coil circuits. Prototype transformers, with a total leakage inductance measured in the secondary of 5 nH, have been tested with peak secondary currents in excess of 600 kA resulting from a 10-kV primary charge voltage. The test procedures and results and the mechanical construction details are presented.

Skin tumors in mice can be induced by the sequential application of a subthreshold dose of a carcinogen (initiation phase) followed by repetitive treatment with a noncarcinogenic tumor promoter. The initiation phase requires only a single application of either a direct acting carcinogen or a procarcinogen which has to be metabolized before being active and is essentially an irreversible step which probably involves a somatic cell mutation. There is a good correlation between the skin tumor initiating activites of several polycyclic aromatic hydrocarbons (PAH) and their ability to bind covalently to epidermal DNA. Laboratory results suggest that bay region diol-epoxides are the ultimate carcinogenic form of PAH carcinogens. Potent inhibitors and stimulators of PAH tumor initiation appear to affect the level of the PAH diol-epoxide reacting with specific DNA bases. Reecent data suggests that the tumor promotion stage involves at least three important steps: (1) the induction of embryonic looking cells (dark cells) in adult epidermis; (2) an increased production of epidermal prostaglandins and polyamines; (3) sustained proliferation of dark cells. Retinoic acid specifically inhibits step two whereas the anti-inflammatory steriod fluocinolone acetonide is a potent inhibitor of steps one and three. The mechanism and the importance of a specific …

In the interaction regions of a relativistic heavy-ion collider, bare, highly charged nuclei pass at great velocities, oppositely moving similar nuclei. Each nucleus, then, sees strong, time varying electromagnetic fields, and it is not surprising that there is a large probability for electron-positron pair creation (a process evaluated many years ago). There is also a smaller probability that the electron of the pair is created, not in a continuum state, but in one of the bound orbits, the K or L or higher orbits, of the Coulomb field of the previously bare nuclei. This dressing is most unfortunate for a collider device, since the charge change leaves the nucleus in an orbit that is no longer appropriate for continuing circulation. This note evaluates the probability for such dressing, and also examines whether a subsequent sweep-off process can undo the first step with any sizeable likelihood. 3 references.

A method employing integral averaging techniques is proposed to aid conduction finite element code users in approximating multidimensional phase change problems such as: (a) liquid solidification under action of surface heat removal such as ice production or solidification of a casting, (b) thermal/chemical decomposition of a solid without removal of degraded material from the remaining virgin material such as charring of wood or reinforced plastics, (c) ablation of solids where the products of decomposition are removed on formation such as melting glass or subliming teflon. Of prime interest to the method is the determination of the amount of material solidified, decomposed, melted or sublimed and the location of the phase change interface as a function of time as it moves through the one-, two-, or three-dimensional finite element mesh. As the interface moves through each element, the energy involved in the phase change process and the difference in heat capacity and conductivity of two phases is accounted for. A method is also included to accommodate convective heat transfer at the moving phase change interface.

A review of the literature indicates that a significant body of descriptive information exists concerning the aquatic ecology of Upper Three Runs Creek and Four Mile Creek of the Savannah River Plant south of Aiken, South Carolina. This information is adequate for preparation of an environmental document evaluating these streams. These streams will be impacted by construction and operation of a proposed Defense Waste Processing Facility for solidification of high level defense waste. Potential impacts include (1) construction runoff, erosion, and siltation, (2) effluents from a chemical and industrial waste treatment facility, and (3) radionuclide releases. In order to better evaluate potential impacts, recommend mitigation methods, and comply with NEPA requirements, additional quantitative biological information should be obtained through implementation of an aquatic baseline program.
